Re: [amibroker] AFL syntax for nested IIF ?

["Ton Sieverding" <ton.sieverding@xxxxxxxxxx>]

Thanks a lot Graham. As I told Herman already there are many ways to Rome. And your's is another one. And of course it works fine but where I was looking for is the syntax of the double array supporting IIF with more than just one action in it. It seems that I got the correct answer from Bill but as I told him there still is a big questionmark for me with those 'AND's. For your information my logical problem again :

IIF(Condition, Do This - Do That - Do Something, Do Nothing)

According to what Bill told me this should have following syntax :

IIF(Barnum > 5, This = 10 AND That = 20 AND Something = 30, Null );

Ton.

  Here is correct and simplest method using IIF to create the array of
  values for each variable
  highbar = iif(barnum < 21, C , null );
  lowbar = iif(barnum < 21, C , null );
  range = iif(barnum < 21, C, null);

  If you are needing to use IF, then this only accepts arrays if you
  place it withon a FOR loop and use array identifiers. But for this
  simple application then IIF is the quickest and simplest way to go.
